1……Rxg2!.

Rxg2 seems strong. If White plays Rxg2 there’s mate in two and in other cases there’s Rxg1+ and Rb8 to protect the bishop (especially if White plays Rc5).
My immediate idea was that I might like to gently push a rook from a2 to a1, threatening Qxg1#. Rxa1? Rxa1+ Bf1 Qf2! would not be a good reply. And not Bf1?, due to both Qf2 (mating) and Bc6+ (gaining queen).
So I try:
1. … Ra1?
2. Rc1!
Hmm…. This is where I find no progress for white.
But from above observations I realize that getting a B check in the diagonal should gain a queen for rook, unprotected as it is on b4.
Therefore it looks like I gain material with:
1. … Rxg2!
With the same mate threat as above.
A)
2. Kxg2? Bc6+
3. Rxc6 Qxb4
B)
2. Rxg2? Ra1+
3. Rg1 Bc6+
4. Rxc6 Qxb4
C) (even worse)
2. Rc1?? Rxg1+
3. Rxg1 Bc6+
4. Rg2 Ra1#
So white has to put a piece on c5 to screen the Q threat against g1.
D)
2. Rc5 (wanting to regain bishop) Rxg1+
3. Kxg1 Rb8! (better than Ra1+ Kf2)
and black is nicely up with bishop.
E)
2. Qc5 (exchange variation) Rxg1+
3. Kxg1 Qxc5+
4. Rxc5 Bxd3
up with bishop and pawn and queens are gone.
Conclusion:
I gain a bishop with:
1. … Rxg2!
2. Rc5 Rxg1+
3. Kxg1 Rb8!
1. … Rxg2 threatens Qxg1#
2. Kxg2
2. Rxg2 Ra1+
3. Rg1 Qxg1#
2. … Bc6+
3. Rxc6 Qxb4 +-
1) — Bc6 !
Offering the Queen
RxBg2 if KxRg2
Bc6+ wins the Q
if RxRg2
Ra1+ Rg2
Bc6+ wins the Q
